Laptop CPU upgrade.

post #1 of 6
Thread Starter 
Hey guys.

I.m looking to upgrade the CPU on my laptop from an i3 380m to, hopefully, a i7 820QM. My laptop is a Toshiba C660 on the most recent BIOS, 6gb of ram (1066mhz bus), 60gb SSD & everything else at stock. Will I have any compatibility issues? Any overheating issues? If so, is it still possible with another quad core CPU?

As always, thanks in advance for the help.

Well, here's the problem most laptops have the CPU soldered in. This is done to save space and weight, that being said the CPU is not removable. In addition to the CPU not being removable, the VRMs are likely rated for nothing more than the i3 so they couldn't handle a quad core i7. The next issue would be that the BIOS is designed for that specific processor often to make the file smaller. So you would need to find or make a new BIOS for the new CPU. Basically there is no way to change the CPU. So if you need a quad core I would recommend a new laptop.

I've already removed the CPU. Its a socket, no doubt. Regarding the custom bios, is there any way to check whether or not it supports i7?

You will have issues. In terms of raw performance, you're better off with an i5-560M or i5-580M. That's a quick 20% gain with same TDP (560M is 2.6ghz stock, 2.93 dual-core turbo, 3.2ghz single-core turbo). The i7-820QM is junk, sorry; but the single-threaded performance is worse than the i3, and it's multi-threaded performance isn't *that much* higher. The biggest problem with 820QM is it's a 45nm quad, while all the Core-i dual-cores are 32nm.

Technically the use the same socket, but unless there are i7-quad versions of your exact laptop model, it's possible Toshiba locked the BIOS to only use i3/i5's (I can't say with certainty). If there is such a lock, it's possible to get a BIOS mod, but that would void warranty and it's a little riskier than a standard BIOS flash. This coupled with the higher power consumption, worse battery life, etc... I wouldn't bother personally.

These responses kill me... FILLED with misinformation. Yeah there are some laptops with soldered in CPUs... this was very common on older ones I believe. The newer ones, more are sockets, at least has been my experience.

As for the cpu, going to the QM, its probably not necessary for a laptop as such, I would think a high clocked dual core i5 would do the trick. That's also not to mention heat differences, etc... and not all CPUs are supported by all laptops.


Jbroad hit it on the head. You will probably save a few bucks too!

The 820QM is considerably faster in every aspect. The i3 doesn't have a turbo boost for the desktop or mobile line so the stock speed is where it stays. However, an i5-560M will be plenty.
